Abstract (en)

A multi-layered film which has a substrate which has at least one layer (A layer) having an ethylene/ alpha -olefin copolymer having a variation coefficient of molecular structural distribution given by the following formula (1) of 0.5 or less <MATH> where sigma is a standard deviation of molecular structural distribution of the ethylene/ alpha -olefin copolymer calculated from the quantities of the components eluted at every predetermined temperature range and the branching degree of each component both obtained by the temperature rising elution fractionation and SCBave. Is an average of the numbers of short chain branches per one thousand carbon atoms in the ethylene/ alpha -olefin copolymer; and an anti-sticking layer which is provided on the substrate and constitutes at least one out of the two outermost layers of the multi-layered film is disclosed.
